Resolving duplicates rows when requesting version

Unless I'm drastically misunderstanding something, I think this is a bug. When resolving and refs contain a version, the resolution data frame unnests the versioned package dependency row into many rows (see reprex below).

library(withr)
library(pkgdepends)

my_resolve <- function() {

  local_options(repos = list(CRAN = "https://cran.rstudio.com" ))
  tmp <- local_tempdir()

  prop <- new_pkg_installation_proposal(
    refs = "rlang@1.0.0",
    config = list(library = tmp)
  )

  prop$resolve()
  prop$get_resolution()
}

my_resolve()

If I'm understanding the package correctly, the proper output should be a data frame with three rows (on Windows at least): the binary, the non-versioned source and the versioned source. Is that correct? The offending column here is metadata. Each new row has a single value of the metadata, which was a list and got unnested. I have a fix in mind if it's okay to make a PR?
